You said you'd done 1000mg of Test before, I read on the IFBB Pro Undercover site that although Test has more aromatising side-effects at low doses than milder steroids like Parabolan and Eq when itcame to big doses the Test was less toxic and easier on kidneys and liver; maybe the same is true of its psychological and HR effects?
Panic Attacks are bad news and yet so many people haven't heard of them or think its 'all in the mind'. A friend of mine who used to have a real coke problem completely lost it once, thoughthe was dying of a heart attack and checked himself into hospital, HR through the roof, flushed, couldn't breathe, anxious, paranoid- the works. They sorted him out but weren't to sympathetic when he explained that a big dose of a Class A kicked it off.
